Your final answer is not how you should ever write a mixed number. You can not simply concatenate the integer +1 and the fraction -3/20 directly to a proper mixed number. The integer part and the fractional part must have the same sign. Change that integer, 1, into a fraction and subtract the fraction numerators to get a valid answer.

Integer you mean the whole number ?
